racemic mixture

A racemic mixture, also called a racemate, is a mixture of equal quantities of the dextrorotatory, d-, or (+) and levorotatory, l-, or (-), forms of an optically active compound. Such a mixture shows no optical activity. Racemic mixtures are denoted by the prefix (±) or dl-.


Racemization is a chemical reaction in which an optically active compound is converted into a racemic mixture.
